The document, which is called "Twitter Shorthand," is literally just a list of nearly 3,000 Internet acronyms and their definitions. Here's one for you: "LOL."

But while it's unclear why the FBI needs to waste resources translating the things like "FWIW," some of them are rather obscure. Take, "BTWITIILWU/BTWITIILWY," which translates to "by the way, I think I'm in love with you." Don't think we'll see members of Anonymous using that one anytime soon though!

We've gone through the list so you don't have to. Here are a few of our favorites.

BEF = best enemies forever/best e-mail friend

BL = belly laughing/bottom line/bad luck

BMT = before my time/basic military training

BRB = be right back

BTW = by the way

DOS = dozing off soon/dad over shoulder/disk operating system

HOH = head over heels/hard of hearing

IFF = if and only if/Internet friends forever/identification: friend or foe
